Changeset 7227 for trunk/psLib/src/fits/psFitsHeader.h

Timestamp:

Message:

psFitsWriteHeader checks that the HDU exists, and creates one if necessary. Added p_psFitsWriteHeader, which does not check. This allows psFitsInsertImage to call p_psFitsWriteHeader, since that already creates the HDU. Was getting into trouble by having psFitsInsertImage create a primary HDU for data, then calling psFitsWriteHeader, which created a primary HDU just for the header (dummy values for BITPIX, NAXIS, etc), then the data couldn't be written out. It would be much better if cfitsio treated data-less PHUs better --- if it recognised an HDU as extant once fits_create_img had been called.
